Ferroptosis Sensitive Neurons is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Ferroptosis-Sensitive Neurons are neurons that are particularly vulnerable to ferroptosis, an iron-dependent form of non-apoptotic cell death characterized by lipid peroxidation. These neurons exhibit heightened sensitivity to ferroptotic cell death due to their unique metabolic properties and antioxidant defense mechanisms. [@stockwell2017]
Overview
Ferroptosis was first recognized as a distinct cell death modality in 2012 and has since been implicated in various neurodegenerative diseases. Neurons are particularly susceptible to ferroptosis due to: [@weiland2019]
High polyunsaturated fatty acid content in neuronal membranes
